Looks like our old friend, Matthias — the developer of the USB SNES cart reader — is back on the scene, and this time he’s going commercial. His newest project, Snega2USB, adds Sega Genesis, read and write for battery-backed SNES games, open source firmware, and up to four gamepads to the homebrew fave of classic gaming fanatics world o’er. This is a work-in-progress, but all the pieces are in place to have all orders met on the December, 2009 street date. Pre-orders will be taken until October 31 for $90 in the United States or €75 in Europe. Video after the break.
